A field experiment was conducted at RARS, Rahmatpur, Barisal during Rabi season of 2012-13 to evaluate the performance of lentil genotypes/lines for searching of high yielding and stemphylium blight disease resistant variety. Twenty two entries and 2 varieties of lentil were used following RCBD with three replications. At maturity stage, 13, 10 and 01lines showed moderately resistant, moderately susceptible and susceptible reaction to Stemphylium blight disease. Results revealed that all the lines statistically different among the genotypes. The line BD-6002 gave the highest yield (1721.0 kg ha-1) followed by BD-3926 and BD-3837 with low disease incidence. The lowest yield (763kg ha-1) was recoded in BD-3979 followed by BD-3834 and BD-3975. So, the lines BD-3926, BD-6002 and BD-3837 may be selected for next year trial.

To search for resistant sources of lentil lines against stemphylium blight disease
A field experiment was conducted at RARS, Rahmatpur, Barisal during Rabi season of 2012-13 for searching high yielding and Stemphylium blight disease resistant variety. Twenty entries of lentil (previously selected from 200 lines in the 1st year) and two check variety BARImasur-1 and BARImasur-7 were evaluated. The experiment was laid out in randomized complete block design with three replications. Line was 2.5m long and spacing was 30cm X 10cm. Seeds were sown in the rows on 26-11-2012. Two weeding were done at 25 days and 45 days after sowing. The crop was harvested within March 07. Data on yield contributing characters were recorded from 10 randomly selected plants of each plot. Disease reaction and grain yield was recorded from the whole plot. Data were analyzed using MSTAT-C program.
Annual Report
The tested lentil variety/genotypes differed significantly from each other in respect of disease, yield and yield contributing characters under field condition. At flowering stage 12 lines showed highly resistant (HR) and 12 lines showed resistant (R) reaction to stemphylium blight. At pod setting stage 7, 16 and 01 line showed resistant, moderately resistant and moderately susceptible respectively, to the disease. At maturity stage, 13, 10 and 01 lines showed moderately resistant, moderately susceptible and susceptible reaction respectively, to Stemphylium blight disease.
